While Windows 7 is doing well among home users, adoption by businesses remains comparably slow. But one research company has an interesting idea for how that might change: it thinks workers used to the system on their home PCs might pressure ... employers to upgrade. While around one in five XP and Vista users overall switched to Windows 7 in its first year (ending October 22), only one in ten businesses are currently running the system.

A Chinese "supercomputer" has been confirmed as the fastest in the world, the first time the country has taken the honor. But the United States is currently working on two machines that could be 10 times faster. The ranking comes from the TOP500 ... project, which produces a list twice a year to show how quickly computers have been proven to work for a sustained period. This is usually much lower than the computer's theoretical maximum speed (which is used in the rare case of tiebreak situations).

Imagine sitting in front of your computer and using hand gestures to control your PC. In the 2002 blockbuster movie "Minority Report," Tom Cruise did just that as he sifted through wads of information using his hands and a 3D computer screen.

Google plans to bar other companies from accessing information in its Gmail service, even with user permission. There's suspicion the scheme is designed to increase competition between Google and social media services such as Facebook. Facebook is ... actually one the best examples of how the change will apply in action.

Microsoft has announced a temporary workaround for users of older editions of Internet Explorer (IE) vulnerable to a new bug. The situation yet again highlights the importance of upgrading to the more secure, recent editions (IE8 and IE9) of the ... browser. The bug's dynamics are all-too-familiar: if a hacker persuades a user to visit a specially-crafted webpage, they'll be able to install and run malicious software on the user's computer. It's another zero day attack , meaning the problem is currently being exploited by hackers before Microsoft has a working fix. Browser Check First, Virus ... (view more)

Five portable devices have become the first certified as 'WiFi Direct,' a new system designed to rival Bluetooth in making it easy to connect devices without wires.

The main solution to that problem has been ... (view more)

Adobe has revealed that there is a critical zero day bug in its Flash Player, Acrobat and Adobe Reader applications. As well as potentially causing a crash, the bug could allow an attacker to remotely take control of a computer. A zero day bug means ... big trouble for a software developer.

Facebook says it has discovered that some application ("app") developers have been deliberately selling user information for the intention of third-party marketing, and has responded by banning a list of developers from the site for six months. A ... similar breach was reported in a Facebook investigation last month .

A well-known Windows virus is spreading to Apple PCs as well. The virus is known as trojan.osx.boonana.a, though it appears to be the same as the so-called Koobface virus which first affected Windows PCs. In both cases the virus spreads through ... social networking sites, most notably Facebook. The virus gets on to computers through bogus messages and one of the most common is some variation on "Is this you in this video?"

Like Facebook before it, MySpace has been accused of privacy violations by sharing user details with third-party advertisers. The new story, published in the Wall Street Journal (WSJ), came after claims the newspaper had kept the article under wraps ... for business reasons.
